INERTIA-OPERATED PUMP.

Application filed February 18, 1922. Serial No. 537,582.

This invention relates to improvements in fuel feed apparatus of a character to be operated by vibrations imparted to the apparatus, it being particularly adapted for use in fuel feed systems for automotive vehicles.

One of the objects of the invention is the provision of means for the above purpose cost, and of a nature not liable to get out ,of order easily. I

Another object of the invention is the pro vision of a pumping means of such charaeter that parts slidable upon each other are eliminated with a consequent elimination of frictionand improvement in pumping efliciency.

Another object'of the invention is the provision of a mounting for the upper end of the guide for the moving column which makes accuracy in workmanship unnecessary.

Another object of thejinvention is the provision of a mounting for the pumping apparatus at an inclination from the vertical by reason of which arrangement we are enabled to take advantage of the vertical components in certain transverse vibrations of the vehicle as well asofvertical vibrations therein. w

Other objects; and objects relating to details of construction and economies of manufacture, will appear as we proceed with the description of that embodiment of our invention which, for the purposesof the presentapplication, we have illustrated in tendmgcolumn 27 having fluid discharge the dash board looking in the direction of I the arrow in Figure I andv showing our tank and pumping apparatus mounted at I an angle.

Similar parts throughout the views.

In Figure Iwe haveillustratated the pret'erred arrangement of the different portions of our fulieed apparatus upon an automobile; 10 be n themam or low level fuel tank, 1.1. the high level or auxiliary referencecharacters refer to like u p p u top 35 of the tank. This guideis preferably made hollow for thesake of the consequent tank and 12 the carburetor. The tank 10 is connected by means of a conduit 13 with the bottom of thetank 11 whiletheconduit 1 1 forms a connection between the carburet- 01-12 and thetank 11 at a position somewhat above the bottom of that tank.

The tank 11 is preferably cylindrical.

At the centralpoint of its base it is provided which shall beof simple construction, small "(611d of which is adapted to be connected the conduit 13 leading to the main tank 10.

The lower portion of the plug has apassage .c

17 the'upper end of which constitutes a seat for a ball check 18 located in a chamber 19 which is closed at the top by a small,

threaded plug 20 having 'perforations'therethrough to connect the chamber 19 with a lower compartment 21 of the tank; Vithin this compartmcntfand along the wall. thereoi is a ring 22 having an upper flange 23 upon the lower compartment 21 and, an upper compartment 25.

The diaphragm by its ownresilience tends normally to assume the position. shown in Figure II, but in order to; assist and reenforce the diaphragm we prefer toemploy a coil spring 26 bearing at its lower endupon the end wall of the tank and at its upper ex upon the lower surface of the diapassages28 therein extending from avalve chamber 29 near the baseof the column. Tlns chamberis closed by means. of a threaded plug 30 having a passage 31 there c which is mounted by'any suitable means a I diaphragm 24 forming the partition between through normally closed by a spring pressed ball Check 32 locatedin the valvechamber The column 27 is cnlarged jto a greater or this enlargementis formed a chamber33.

The walls ofthe chamber embrace with a sliding lit a guide 34 depending from the saving inweight. It is closed at its upper end by a threaded plug 36 having an upper ios lesser-extent at its upper end and'within 5 Our auxiliary tank 11 of mn'uichine screw 3 extending throu 'h' e. hole in the top of son'mwlnit grziter dizuncter than the diz'uneter of the screw.
